Some keyboards (like Aula F75 and Apple keyboards) have function keys (F1-F12) that don't work properly in Linux because they're incorrectly detected or configured to prioritize media keys over standard function keys.
- Function keys (F1, F2, F3, etc.) don't respond or trigger media functions instead
- Keys work as media controls (volume, brightness) by default instead of F1-F12
